Because we made copies, we want to remove duplicate file.
1. We'll remove newlist2.txt:del newlist2.txt <ENTER>
newlist2.txt
del newlist2.txt <ENTER>
2. You can remove now all files by typing (Make sure you are in the right folder, there's no undo in the command line!):del *.* <ENTER>
del *.* <ENTER>
(or simply: del . <ENTER>)
del . <ENTER>
3. Now remove the directory John (remember how to do that?).
